I am using SWD programming everyday, but with higher speeds 20000-25000, and yapicoprobe instead of debugprobe (the warnings are OK).What's the recommended way to do mass production programming for an RP2350 based product with no exposed USB port?
I imagine a Pi debug probe connected to SWD pads on the production board via a bed of nails will work. I could use a command like:
openocd -s tcl -f interface/cmsis-dap.cfg -f target/rp2350.cfg -c "adapter speed 5000" -c "init; reset halt" -c "flash write_image erase myimage.bin 0x10000000" -c "flash verify_image myimage.bin 0x10000000" -c "shutdown"
Can this be improved on in terms of speed and reliability, or anything else? I've got almost no experience of production line environments, so am worried.
The command looks like:
openocd -s .pico-sdk/openocd/0.12.0+dev/scripts -f interface/cmsis-dap.cfg -f target/rp2350.cfg -c "adapter speed 25000; program "<IMAGE.elf>" verify reset exit"
